Oxygenation Nursing Practice Questions Questions
Question 1 of 5
The nurse is caring for a client with a tracheostomy. Which finding requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because oxygen saturation of 88% indicates hypoxemia, which requires immediate intervention to prevent complications. Hypoxemia can lead to tissue damage and organ dysfunction. Oxygen therapy is needed to improve oxygen saturation. Choices A, C, and D are not as urgent. Mucus in the tracheostomy tube can be suctioned, mild redness can be monitored for infection, and effective coughing indicates airway patency.
Question 2 of 5
A patient hospitalized with chronic obstructive pulmonary disease (COPD) is being discharged home on O2 therapy. Which instruction should the nurse include in the discharge teaching?
Correct Answer: C
Rationale: The correct answer is C because O2 therapy can indeed improve a COPD patient's prognosis and quality of life by providing supplemental oxygen to help with breathing. Increasing O2 flow without healthcare provider guidance (B) can be dangerous. Travel is possible with portable O2 devices (A). O2 is stored in small tanks or concentrators, not large metal tanks lasting 4-6 hours (D).
Question 3 of 5
The nurse is caring for a patient with newly diagnosed tuberculosis (TB). What is the most important instruction to include in the teaching plan?
Correct Answer: B
Rationale: The correct answer is B: Take medications exactly as prescribed for the entire course. This is crucial in treating TB to prevent drug resistance and ensure the infection is fully eradicated. Choice A is not necessary as TB is not transmitted through the air. Choice C is not needed unless the patient is in close contact with others. Choice D is not specific to TB treatment and may cause unnecessary social isolation.
Question 4 of 5
The nurse observes continuous bubbling in the water-seal chamber of a patient's chest tube. What should the nurse do?
Correct Answer: B
Rationale: The correct answer is B: Check the system for air leaks. Continuous bubbling in the water-seal chamber indicates an air leak in the system. Checking for air leaks is important to prevent complications like pneumothorax. Clamping the chest tube (A) can cause tension pneumothorax. Adding more sterile water (C) can disrupt the system's balance. Notifying the healthcare provider (D) should be done after checking for air leaks.
Question 5 of 5
Which patient statement indicates a need for additional teaching about oxygen therapy?
Correct Answer: B
Rationale: The correct answer is B because increasing oxygen flow rate without healthcare provider approval can be dangerous, leading to oxygen toxicity. Choice A shows good understanding of smoking risks with oxygen therapy. Choice C demonstrates awareness of equipment maintenance. Choice D indicates compliance with the provider's instructions. However, B is the only statement that suggests a potential misunderstanding of oxygen therapy management.
